FEED-CUP FOR FERTILIZER-DISTRIBUTERS.

SPECIFICATION forming part of Letters Patent No. 243,716, dated July 5, 1881.

Application filed September 10,1ss0. (Model) To' all whom it may concern Be it known that I, WALTER MARKs, of Ohapinville, Ontario county, New York, have invented an Improvement in Feed Cups for Fertilizer-Distributers, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a central vertical section of my improved feed-cup for fertilizer-distributers on the line it 00, Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is a plan view, showing the upper end of the hollow spindle of the supporting-frame. Fig. 4 is a transverse section throughthe hollow spindle of the supportingframe, on the line y y, Fig. 1. Fig. 5 isaside view of my improved feeding-shell, showing, also, the distributer. Fig. 6 is a view of my improved feeding-shell as seen from below. Fig. 7 is a side view of the detachable key for connecting the feeding-shell to the hollow spindle. Fig. 8 is a central vertical section of the same on the line 2 2, Fig. 2. Fig. 9 is a side elevation of my improved feeding-shell as seen from the direction :in dicated by the arrows at, Figs. 1 and 2. Fig. 10 is a transverse section of my improved feeding-shell on the line or at, Fig. 5. Figrll is a plan view of a modified form of my improved feeding-shell. Fig. 12 is a transverse section of the same on the line 00 m, Fig. 11. Fig. 13 is a side elevation of the same as seen from the direction of the arrow at, Fig. 11. Fig. 14 is a vertical section of the same on the line y y, Fig. 11. Fig. 15 is a side elevation of the same as seen from the direction indicated by the arrow at, Fig. 11. Fig. 16 is a transverse section through and at right angles with the radial arm of the feedcup.

My invention relates to an improvement on the devices shown in Patent No. 213,053, and Patent No. 217 ,628; and it consists in providing the feeding-shell with a projecting lip having a recess underneath its upper side for the purpose of facilitating the distribution of the fertilizer.

My invention also consists in providing a dome-shaped feeding-shell with a projecting recessed lip.

' My invention also consists in the combination of a dome-shaped feeding-shell with a central projecting lug on its upper side and a distributor fitted on the projecting lug.

My invention also consists in an improvement in the form of the radial arm of the feedcup.

My improvements on feed-cups for fertilizerdistributers are represented in the accompanyin g drawings, in which A is the feeding-shell; B, the supporting frame; 0, the spindle of; the same; D, the detachable key; distributer.

The rotating feeding-cup E is carried by the supporting-frame B, and is given arotary'motion thereon by means of the bevel-pinion b on the horizontal shaft 01 meshing with the bevel-gear e on the lower side of the feed-cup. The supporting-frame B is provided with suitablelateral arms for attachment to the bottom of the feed-hopper, as represented in Fig. 2. The supporting-frame B extends downward,

E, the feeding-cup, and F the and is made of a form to support the bevelb and shaft d, as represented at ff, Figs. 1 and 2. The feeding-shell A is attached to the upper end of the spindle O, and remains station ary with it during the operation of the ma-' chine, while the feed-cup E revolves about it in the direction as indicated by the arrow h, Fig. 2. The spherical or dome-shaped feedcup A. is provided on one side with the projecting lip g, the forward edge of which is inclined upward from the bottom of the feed- V 9,-forthe admission of the fertilizer from the interior of the rotating feed-cup into the feed-' ing-shella Behind the opening 2' the projectshell, so as to'make an opening, '6, Figs. 5 and" ing-lip g is bent or curved upward, forming a recess,'l, Figs. 10 and 12, for the purpose of preventing the adhesion of the fertilizing material to the interior of the feed-shell immediately behind the forward edge of the projecting lip g, and thereby securing a uniform rate of discharge of the fertilizer. The recess 1 may also be applied with great advantage to a feeding-shell having a flat upper surface, as shown in Figs. 11, 12, 13, 14., and 15. This flat or curve-shaped recess given to the under side of the projecting lip effectually prevents the fertilizing material from pasting or adhering to the interior of the feeding-shell, as the fertilizer, in passing through the opening 6, takes the direction approximately indicated by the arrow m in Fig. 10. The recess may be of greater or less depth, as indicated in. the

drawings, and it will be found in practice more convenient to use a shallower recess on a feeding-shell having a fiat upper surface than on a dome-shaped feeding-shell. It is not necessary that the recess should extend entirely across the projecting lip of the feeding-shell in the direction of the dotted line as as, Fig. 11, but a shorter recess will answer the purposes of the invention.

The feeding-shell A is removably connected with the spindle G by means of the key D. The feeding-shell is provided centrally on its interior surface with a ring, a, which fits the upper end of the spindle 0. Inside the ring it the feeding-shell is provided with a slot, 0, to receive the key D. The upper end of the spindle O is provided with a key-shaped opening, t, as represented in Fig. 3. Below this opening a recess of larger size than the opening is made in the spindle, as indicated by the dotted lines p in Fig.3.

The key D consists of an upper curved bar, q, of the same width as the slot 0, a straight shank, r, and a projecting lug, s. The spindle and lug of the key are of a size and form corresponding to the key-shaped opening t in theupper end of the spindle 0. When the shank r and lug s are inserted in the opening in the spindle G and partially rotated the outer end of the lug 8 passes underneath the lip formed by the recess p in the upper end of the spindle O and engages therewith, thereby securing the shell upon the top of the spindle. The bar q is longer than the slot 0 in the top of the feeding-shell, so that its ends bear upon the shell and secure it in place. Thelip formed by the recess 19 may be beveled or screwshaped, for the purpose of causing the key D, when inserted into the spindle and partially rotated, to draw the feeding-shell down on the top of the spindle.

In Fig. 5 I have represented a distributer, F, as applied to the upper side of my improved dome-shaped feeding-shell. The ends of the distributer F are attached to the interior of the feed-cup E by springing the metal rod which constitutes the distributer into holes in the interior of the feed-cup or in any other convenient manner. At its center the top of the dome-shapedfeeding-shell is provided with a projecting lug, c, for the purpose of sustainin g the distributer in position. The distributer may be fitted to the projecting lug c in any convenient manner. In Fig. 5 the distributer is represented as formed of a wire, which is bent in the center into a ring, which fits over the lug c. The bottom of the feed-cup is open inside the ring 0; of the supporting-frame B, as represented at u n, Fig. l, with the exception of the three radial arms shown in dotted lines to w w, Fig. 2, which connect the exterior of the feed-cup with the central ring, 61, Fig. 1.

Inside the ring 41 c the supporting-frame B consists of a horizontal plate, upon the upper surface of which the radial arms to w w rotate, except that between the lines 6 6, Fig. 2, an opening is made through the plate, slightly in the rear of the projecting lip g, for the purpose of permitting thefertilizer to pass through the supporting-frame. The plate may be provided with other openings, for the purpose of securing lightness; but the plate should, however, be solid or without perforations for a short distance below or in front of the line 0, Fig. 2.

It is evident that the detachable key D may be employed with any form of feed-shell.

In Fig. 16 I have represented atransverse section through and at right angles with the radial arms to of the feed-shell. The radial arm slides over the supporting-frame B in the direction indicated by the arrow in Fig. 16, and the under side of the radial arm is beveled or inclined upward, as here represented, for the purpose of reducing the surface of frictional contact, and for preventing the adhesion or pasting of the fertilizer to the upper side of the supporting-frame.

I I claim- 1. The feeding-shell A, provided with the projecting lip g, the under surface of which is inclined upward behind the feed opening, thereby forming the recess l, to prevent the adhesion of the fertilizer thereto, substantially. as and for the purposes set forth.

2. The combination of the rotating feed-cup E, dome-shaped feeding-shell A, having cen tral lug, c, and distributer F, substantially as described.

4 3. In combination with the feed-cup E and supporting-frame B, the radial arms 20, having their lower surfaces beveled upward, substantially as described.
